Background | It is a multi-target VEGF and PDGFR receptor family inhibitor. |
Biological Activity | Linifanib (ABT-869) 是一种多靶点 VEGF 和 PDGFR 受体家族的抑制剂,抑制KDR,Flt-1,PDGFRβ和FLT3的 IC50 值分别为3,4,66,4 nM。[1] |
IC50 | KDR:4nM;PDGFRβ:66nM;Flt-1:3nM;FLT3:4nM [1] |
In Vitro | 对于VEGF和PDGF受体家族的成员,Linifanib显示IC50值为4nM(KDR)至190nM(FLT4)。 Linifanib对TIE2和RET的作用较小,但对其他非相关酪氨酸激酶(如类固醇受体辅激活因子和表皮生长因子受体)的活性较低(IC50>10μM)。在用于表达人KDR的3T3鼠成纤维细胞中,Linifanib抑制VEGF诱导的KDR磷酸化,IC50为4 nM。当HUAEC用作靶细胞时,Linifanib可观察到抑制受体自身磷酸化的类似效力。 Linifanib在10 nM时完全抑制VEGF刺激的KDR磷酸化,在3 nM时完全抑制70%(IC50 = 2 nM)[1]。 |
In Vivo | Linifanib在VEGF诱导的子宫水肿(ED50 = 0.5 mg/kg)和角膜血管生成(> 50%抑制,15 mg/kg)的基于机制的鼠模型中有效口服。 ABT-869在人纤维肉瘤和乳腺癌,结肠癌和小细胞肺癌异种移植模型(ED50 = 1.5-5mg/kg,每天两次)中显示出功效,并且在原位乳腺和神经胶质瘤模型中也是有效的(> 50%抑制)。分别在表皮样癌和白血病异种移植模型中观察到肿瘤大小减小和肿瘤消退[1]。 |
Cell Experiment | 将HUAEC以每孔2,500个接种到96孔板中,并与无血清培养基一起温育24小时。加入Linifanib和VEGF(最终,10ng/mL)并在无血清培养基中温育72小时。对于癌细胞系,每孔2,500个在完全生长培养基中过夜。在完全生长培养基中将Linifanib加入细胞中并孵育72小时。对于白血病细胞,通常将50,000个孔置于完全生长培养基中,加入药物并孵育72小时。通过添加Alamar Blue(最终溶液,10%),在37℃下在CO 2培养箱中孵育4小时,并在荧光板读数器中进行分析来确定对增殖的影响[1]。 |
Animal Experiment | 小鼠:将携带肿瘤的动物分成组(n = 10),并开始以指定剂量给予载体(2%乙醇,5%吐温80,20%PEG400,73%盐水)或抑制剂(Linifanib)。通过用卡尺测量肿瘤大小并计算大小来评估侧腹中的肿瘤生长。使用磁共振成像[1]确定原位胶质瘤模型的肿瘤体积。 |
Kinase Experiment | 对于酪氨酸激酶测定,含有单一酪氨酸的生物素化肽底物与1mM ATP,Eu-穴状化合物标记的抗磷酸酪氨酸抗体(PT66)和链霉亲和素-APC一起用于均相时间分辨荧光测定。使用5μMATP,[33P] ATP和具有肽捕获的生物素化肽底物测定丝氨酸/苏氨酸激酶,并使用SA-Flashplate测定33P的掺入。通过连续稀释化合物的DMSO储备溶液制备多种浓度的Linifanib。使用浓度响应数据的非线性回归分析计算导致50%活性抑制的浓度[1]。 |
